Why would you look up enemy patterns?
Anyway, I played Fate/Extra back then, and I'm playing it again right now.
Well, actually, it's Fate/Stay Night Realta Nua > Forest > Fate/Extra in terms of priorities.
I'm nearing completion of Realta Nua anyway.
So the thing is, it's basically rock-paper-scissors.
The exciting part is in beating other Servants.
If you were also interested in how things worked in F/SN, then the way things work in Fate/Extra will interest you as well.
Also, the main difference between Red Saber and Arturia are the way they dress and their boobs.
Yep. Boobs.
